NUT-LOCK WASHER.

SPECIFICATION forming part of Letters Patent No. 616,969, dated January3, 1899.

\ Application filed August 22, 189 8. $erial No. 689,256. (No model.)

To all whom it may concern.-

Be it known that I, LTZA PYLE, a citizen of the United States, residingat Ross, in the county of Campbell, State of Kentucky, have invented anew and useful Nut-Lock WVasher, of which the following is aspecification.

My invention relates to improvements in nut-lock washers in which thewasher con sists of a combination of rubber and metal of such a form andshape that when the same is fixed in place the WtSllGlbGCOlIlQSstationary and the nut when brought to its base has so embedded itscorners into the rubberportion of the washer as to make it (the'nut)permanently fixed in position.

The objects of my improvement are, first,

companying drawings, in which Figure 1 presents the top view of therubber part of the washer for use upon railjoints in railroads; Fig. 2,the metal part or cup prepared to receive the rubber part for use onrail-joints in railroads; Fig. 3, the

7 complete washer for use on rail-joints; Fig.

4, a section of a rail-joint, showing three different stages in theapplication of the washer; Fig. 5, a sectional view of the rail-jointwith the washer being slipped into place; Fig. 6, a sectional view ofthe rail-joint with the washer in its proper position preparatory to theputting on of the nut; Fig. 7, a sectional view of the rail-joint withthe nut and washer both in place.

Similar letters refer to similar parts throughout the several views.

The rubber e and metallic cup F constitute the several parts of thewasher for use diameter of which being equal to the shortest outerdiameter of the nut d, so that the points of nut cl when being screwedhome will embed themselves into the rubber e, as shown in Figs. 4; and7. The cup F is made of some metallic substance, giving it strength anddurability, having through it the hole 0 to receive the bolt 0.Extending downward from the hole 0 is the projectionf of the metallicportion of the washer, which is of such a length from the center of thehole 0 to the base of the projection as to permit the washer to passover the bolt 0, thus making the base of the projection f rest upon theflange or lip of the fish-plate b, as shown in Fig. 4, making the washerfixed in position with respect to revolving about the bolt 0. Around thetop of the cup F are the points g, which are of less length than thewidth of the rubber 6, so that when they are bent down and. sunken intothe rubber e, as indicated in Figs. 7 and 3, the rubber 6 will bestationary within the cup F and at the same time the points g will notinterfere with the corners of the'nut d embedding themselves into therubber e. The sides G of the cup F when the washer is completed for useare of as much less thickness, than the nut d as will not interfere withthe free use of the wrench upon the nut d, as shown in Fig. '7. Thewasher when thus constructed and put in place over the bolt 0 becomesstationary with respect to the motion of the nut cl, whereas the cornersof the nut 01 when it is screwed home have embedded themselves into Ithe rubber 6, thus making for the nut 01 a rubber jacket of the shape ofthe nut, as shown in Fig. at. Having thus described my invention, thatwhich I desire to secure by Letters Patent The combination of the rubber6 with the metallic cup F held firmly together by the points g beingsunken into the rubber e so Witnesses:
